Earth's magnetic field shields us from deadly cosmic radiation, and without it, life as we know it could not exist here. The motion of liquid iron in the planet's outer core, a phenomenon called a "geodynamo," generates the ...

The most direct information about the interior of the earth comes from measuring how seismic acoustic waves—such as those created by earthquakes—travel through the earth. Those measurements show that 95% of the earth's ...

There have been many estimates for when the earth's inner core was formed, but scientists from the University of Liverpool have used new data which indicates that the Earth's inner core was formed 1 - 1.5 billion years ago ...

Researchers at the University of Utah have discovered a new aquifer in the Greenland Ice Sheet that holds liquid water all year long in the otherwise perpetually frozen winter landscape. The aquifer is extensive, covering ...

(Phys.org) —A trio of researchers from France and Denmark has combined data obtained over the past several centuries to create a model depicting the westward drift of the Earth's magnetic field. In so doing as they explain ...

(Phys.org) —A trio of researchers working in Spain suggests in a paper published in the journal Nature Physics that the surface of some neutron stars might be "lumpy." Stars with such a surface might help explain, they ...

The massive ball of iron sitting at the center of Earth is not quite as "rock-solid" as has been thought, say two Stanford mineral physicists. By conducting experiments that simulate the immense pressures deep in the planet's ...
